Looking through the shelves of my LGS I've seen that they still have ample supplies of .38 Super. After reading more of Elmer Keith's Sixguns (Thanks Amazon Kindle!), he seems to keep 38 Super in high regard and often puts it to a higher pedestal to 9mm Parabellum.
I'm getting the impression that .38 Super is the go-to caliber for folks that can't have reasonable access to 9mm and still want a high velocity 9mm/.38 caliber cartridge.
I've only really seen 1911 clones (and older manufactured Colts) chambered in this cartridge. In comparison, .380 ACP, which performs a similar role, is very popular in modern self defense handguns.
So, what's the deal with .38 Super? Is there any reason why it's not as popular as most high velocity cartridges?
I'm not looking to get something chambered in this caliber any time soon but this subject has piqued my interest as I've been moving through Sixguns.
